All The PCCN Exam Questions and Answers(Verified Answers)
1.The nurse observes that the patient's jugular veins distend in the semi-
up- right position to more than 5 cm above the sternal angle. This is an
indication of (Answer) fluid volume overload.
2.what is normal Pulmonary artery occlusion pressure (PAOP) (Answer) 5-
12 mmHg
3.The resistance against which the left ventricle must pump to eject its volume is (Answer) systemic vascular resistance.
4.When the tricuspid valve is open, central venous pressure reflects the filling pressure in the (Answer) right ventricle.
5.Tachycardia is dangerous for the patient with ischemic heart disease because of (Answer) compromised cardiac output. .During initial examination of a critical care patient, the nurse observes wide and convex nails and bulbous fingertips. This is evidence of (Answer) central cyanosis.
7.Priorities for palpation of the patient with cardiovascular disease include:-
: estimating edema.
checking capillary refill checking for DVT arterial pulses
8.By blocking the conversion of angiotensin I to angiotensin II,
an- giotensin-converting enzyme inhibitors produce (Answer) b.
vasodilation.
9.The nurse has read that the cardiologist recommends the use of class IV
drugs to depress sinus and atrioventricular node conduction and

17.What procedure secures an arteriovenous malformation when a pt's condition is too unstable for surgery (Answer) embolization that can be done to secure the lesion without surgery. When the condition is more stable, an operation might be considered if needed.
